Next.js supports dynamic import(), which allows you to import JavaScript modules (including React components) dynamically.
Each dynamic import is loaded as a separate chunk, enabling component-level code splitting.
By using dynamic imports, you can control resource loading so that users only download the code they need for the part of the site they’re currently viewing1.
Benefits of Dynamic Imports in Next.js:
Improved Performance: Smaller chunks lead to faster page loads, especially for large codebases.
Reduced Initial Load Time: Components are only loaded when required (e.g., when a user navigates to a specific page).
Better User Experience: Users get a more responsive site with quicker content rendering21.
Implementing Dynamic Imports in Next.js:
To use dynamic imports, you can leverage the dynamic function provided by Next.js.
Example :
import dynamic from ‘next/dynamic’;
const MyDynamicComponent = dynamic(() => import(‘../components/MyComponent’));
In this example, MyDynamicComponent will be loaded only when it’s needed, improving performance and resource utilization3.
